Answer: 147, 76 and 56.5
Step-by-step explanation:
11, and 12
Both of these questions require that you find the sum of both angles, and you know this because an angle written down starts with an outside point, a middle point then another outside point. So n, the left side, p the middle, and q, the outside. You add everything in between, the 78 and 68, and you get 147.
13
13 is different because a straight line is equal to 180 degrees, we know this because a full circle is 360 degrees and you split in in half with a straight line going through the center and you get 180 degrees on each side, so with this one you just take 180 - 23.5, and you get 56.5!
Let g represent the number of gallons to be drained. Then the amount (in gallons) of bleach in the tank will be given by
.. 4%*(120 -g) +100%*g = 7%*120
.. 4.8 -.04g +g = 8.4
.. 0.96g = 3.6
.. g = 3.6/0.96 = 3.75
3 3/4 gallons need to be drained and replaced with 3 3/4 gallons of bleach.

Answer:
Total number of Hyenas is 19
Step-by-step explanation:
Given
Total number of Lion + Hyenas= 34
Let Number of Hyenas be x
Number of Lions = 34 -x
Now According to question
Each lion eats 4 antelope + Each Hyena eats 3 antelope = 117
![4(34-x)+3x=117\\136-4x+3x=117\\136-x=117\\136-117=x\\\therefore x = 19](https://tex.z-dn.net/?f=4%2834-x%29%2B3x%3D117%5C%5C136-4x%2B3x%3D117%5C%5C136-x%3D117%5C%5C136-117%3Dx%5C%5C%5Ctherefore%20x%20%3D%2019)
Hyenas = 19
Lions = 34-19 = 15
I think the answer is C or A
